摘要
在CARDC4m ×3m 低速风洞中应用的大攻角连续扫描试验技术克服了以往在低速风洞中进行的常规步进攻角静态试验效率低,试验结果信息量少的缺点,实现了对飞机模型的气动量在整个攻角试验范围连续测量,完整地描述了模型的大攻角静态气动特性,为型号研制提供了丰富的风洞试验结果。笔者结合某型号飞机试验。
In the past, the aerodynamic loads on test model in the wind tunnel were generally measured through the step by step test. But, there existed some disadvantages in this kind of test technique, such as, the test efficiency was not as high as we expected and the result information was not as much as we wanted. Now, the continuous scan test technique which was put into use in 4m×3m wind tunnel of CARDC could overcome these shortcomings. This technique can survey the aerodynamic loads continuously within the whole range of angles of attack in the high rate and discover the characteristics of model's static aerodynamic loads completely. In this paper, An application of continuous scan test technique to the fighter model is introduced.
